Smaller towers......yes! We've already seen quite a few of the slower, smaller towers become privatized, and there are still plenty of the small to medium sized facilities that could very easily follow suit, but I sincerely doubt that the bigger, busier towers, tracons, and centers will become privatized; at least not in my lifetime anyway. There's been talk here and there, specially when the Republicans are in control, but in the end, our country is so obsessed with accountability, and security that there's no way congress will turn over control of our airspace to private interests.
